LUBRlCATOR-FEED REG U LATOR.

SEECIFICATION forming part of Letters Patent N 0. 675,204, dated May 28,1901.

Application filed March 20, 1901. Serial No. 52,069. (No model.)

T0 at whom it may concern:

Be it known that I, FRANK W. EDWARDS, a citizen of the United States,residing at Logansport, in the county of Cass and State of Indiana, haveinvented certain new and useful Improvements inLubricator-FeedRegulators, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to certain new and useful improvements inlubricators, and more especially pertains to the feed regulatorstherefor.

The invention has for its objects, among others, to provide a simple,cheap, yet durable and most efficient device for regulating the travelof the valve-stem, to make provision for the adjustment of the parts,and to insure a predetermined amount of flow of the lubricant, so thatsuch amount of flow is assured until readjustment is made. By myconstruction the travel of the valve can be regulated to permit acertain amount of the oil to escape, so that after the device has beenonce regulated to any predetermined quantity of flow of the lubricant itrequires no more attention from the engineerthat is, whenever the engineis to lubricated it is only necessary for the engineer to turn thevalve-stem and the predetermined quantity of'oil will flow. The engineercan shut off the lubricator atnight or at any other time and open itagain at the same fixed distance, so as to insure a flow of apredetermined quantity of the lubricant. I go further in this connectionand provide a construction whereby both an adjusted and a full-open feedare provided, in connection with an assured and positive means oflooking it when set to a fine feed.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure 1 is a substantially centralvertical section with parts in elevation, showing my improved adjustablefeed-valve and its connections with the lubricator. Fig. 2 is asubstantially centrallon gitudinalsection through another embodiment ofthe invention.

Like letters of reference indicate like parts in both views.

Referring now to the details of the drawings by letter, A designates aportion of the wall of the lubricator, of known construction, of whichBis the oil-delivery pipe, communicating with the passage or in thefeed-arm O, which in this instance is shown as the lower feed-armthreaded into a suitable openingin the Wall of the lubricator andprovided with a valve-seat c, controlling the outlet of the oil orlubricant through the opening 61 in the cone D. E is the nipple forattachment of the sight-feed, and F is a drain-passage controlled by thevalvef, all these parts being of any well-kn own or approved form ofconstruction in lubricators.

G is the valve, fitted to the valve-seat c to control the flow of theoil through the delivery-opening d, and the valve-stem g-is threaded fora portion of its length, as seen at g, and has threaded engagement inthe threaded bore h of the nipple H, depending from the feed-arm, asclearly seen in Fig. 1. This nipple is exteriorly threaded, as shown ath, and is threaded into the upper enlarged portion of the nut I, whichnut is provided with the threaded extension '5, through the bore ofwhich works the unthreaded portion of the valve-stem. The valve-stem isprovided with a suitable handle or analogous means j, by which it may beturned, as illustrated.

K is a jam-nut threaded onto the threaded extension 7 of the nut I, asillustrated, and L is another jam-nut, likewise threaded upon theextension *6 of the nut I beneath the nut K, and this latter nut L hasthe extended sleeve Z, which is recessed, as shown, so as to be out ofengagement with the extension of the nut I, and the lower end of thisextended sleeve terminates in or is provided with the handle M and thestop m. The valve-stem 9 near its lower end, within the sleeve of thenut L, is reduced or otherwise constructed to form a stop-shoulder N, asclearly illustrated in Fig. 1.

The operation of the parts just described is as follows: Supposing thevalve to have been set so as to make a slight opening and the engineerdesires to open the valve wide for a while, he grasps the handles j andM and turns them together until the required amount of oil is let out.He then turns both of the said handles up until the nut L comes incontact with the jam-nut K, which forms a lock. The valve-stem g is thenturned down until the stop-shoulderN comes in contact with the stop m,which brings the parts back to the same adjustment that was had beforethe valve was opened wide. It will thus be seen that while I can adjustthe parts to permit of the flow of any predetermined amount of oil andinsure the flow of such amount at any and all times until the parts arereadjusted I also provide for the opening of a valve to admit of agreater fiow at any time when desired and then again restore the partsto their normal position to allow of the flow of the first predeterminedamount.

In Fig. 2 I have shown another form of embodiment of the invention sofar as pertains to the adjustment for a flow at all times of apredetermined amount of the lubricant. In this figure the nut O isprovided with the extended sleeve 0, within which sleeve are the jam-nutP, the equivalent of the jam-nut K in the form shown in Fig. 1, and thejam-nut Q, the equivalent of the nut L seen in said figure. The valve Rin this form controls the flow of oil through the discharge-opening f,and the valvestem is provided with a suitable handle or turning meansSand is threaded into the lower part of the extension-sleeve of the nut0, while its upperend is threaded into the extension 8 from the lowerfeed-arm. The operation is as follows: The nuts P and Q are adjusted soas to allow of a predetermined amount of movement of the valvestem tounseat the valve to permit of the flow of a predetermined amount of thelubricant, and this amount of flow is assured at all times until theparts are readjusted, as they may readily be, as will be clearlyunderstood, to increase or decrease the flow of the lubricant.

It will be seen that I have devised a simple, cheap, yet reliable andefficient means for regulating the feed-valve and the feed, and whilethe embodiments of my invention as hereinbefore disclosed are what Iconsider at the present time to be preferable I do not wish to beunderstood as limiting myself to the details herein illustrated, butreserve the right to make such changes, variations, and modifications asmay come clearly within the scope of my invention and the protectionprayed.

WVhat is claimed as new is 1. In a lubrieator-feed regulator, thecombination of a valve, a nut having an extension, avalve-stem movabletherethrough, and independent jam-nuts, with a cooperating stop device,as and for the purpose specified.

2. In a lubricator-feed regulator, a valve, a nut having an extension, avalve-stem movable through said extension, and jam-nuts interposedbetween the first-mentioned nut and the lower end of the extension, anda cooperating stop device, substantially as described.

7. In a lubricator-feed regulator, the combination of a valve, avalve-casing having a depending threaded sleeve, a nut adjustablethereon and having a depending sleeve, ajamnut on said sleeve, and anindependent jamnut on said sleeve beneath the first-mentioned jam-nut,and a cooperating stop device, the lowermost jam-nut and the valve-stemhaving handles adapted to be simultaneously actuated, substantially asdescribed.

8. In a lubricator-feed regulator, the com bination of a valve, avalve-casing having a threaded extension, a nut screwed on saidextension and having a dependingscrew-threaded sleeve, a jam-nutadjustable on said sleeve, and an independent jam-nut also adjustable onsaid sleeve and having a depending portion provided with a handle, and avalvestem having a handle adapted to be grasped simultaneously with thehandle of the lowermost jam-nut and provided with a shoulder serving asa stop in conjunction with a portion of the handle of the lowermostjam-nut, substantially as described.
